GEAR-CASING.

SPECIFICATION forming part of Letters Patent No. 635,024, dated October 17, 1899.

. Original application iiletl January 21, 1898, Serial No. 667,441. Divided and this application filed February-2 7, 1899. Serial No. 706,969. (No modeldV To @ZZ whom, t may concern,.- l

Be it known that we, MARSHAL T. REEVES, JOHN N. KAILoR, and HARRY C. CLAY, citizens of the United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented a new and useful Gear-Casing, of which the following is a speciiication.

Our invention relates to an improvement 1o in gear-casings, and the present application is a division of our original application for patent for a pneumatic stacker filed January 2l, 1898, Serial No. 667,441.

The object of our invention is to provide i5 an improved form of casing for gears, particularly of the gears used for driving the fan of a pneumatic stacker.

The accompanyingdrawings illustrate our invention. v

zo Figure 1 is a perspective View showing the gear-Casin g in position on the fan-easing. Fig. 2 is a horizontal section through the center of the driving and fan shafts. Fig. 3 is a vertical section. Fig. i is a section on line 4 4 2 5 of Fig.- 3.

The casing consists of two registering sections 5 and 6, provided with anges 7 and 8, respectively, by means of which they may be bolted together and to the fan-casing 9. Sec- 30 tion 5 is provided with a cup-shaped portion 10, having a bearing 1l, arranged to receive fan-shaft 12, a gear 13 being mounted on said shaft within the portion 10. Another bearing 14; is also carried by section-5 in posi- 3 5 tion to receive the drivingshaft 15, to the inner end of which is secured a gear 16, arranged to mesh with gear 15. For convenience the bearin gs 11 and 14 should be capped bearings of any desired form. Section 6 isV provided with a cup-shaped portion 17, which is adapted to register with portion of secn tion 5, and in this portion 17 is carried a step-v forming two chambers 22 and 23, the bearing 14 being located in chamber 23. The bottom of chamber 23 is lower than the bottom of chamber 22, and a small opening 24 is formed through wall 21 lat the bottom of chamber 55 23, so as to allow any oil which may passv into chamber 23 to return to chamber 22.

For convenience in examining the bearings a door 25 leads into chamber 22, andl a door 26 leads into chamber 23, both doors being 6o preferably hinged upon section 6. ln order that bearing 11 may be easily oiled, a pipe 27 is provided, said pipe leading from the openi ing closed by door 25 to said bearing. In order to prevent oil from being thrown out by the gears through the opening closed by door 25, aguard 28 is carried by section 6.

In use enough oil is placed in chamber 22 to come up into contact with the gears. Wall 21 prevents any great amount of oil 7o from working out along bearing 14. Any surplus oil in bearing 14 will drop to the bottom of chamber 26 and return throughopening 24 to chamber"22- By this construction the gears may be con- 7 5 tinuaily flooded with oil, which is nevertheless retained within the casing, and the gears and bearings are thoroughly protected from dust and dirt.

XVe claim as our invention- 8o 1. A gear-casing consisting of the following elements; a cup-shaped section carrying a pair of shaft-bearings one at an angle to the other, and a registering section arranged to inclose and cover both-of said bearings and. to form with the first section a chamber for the reception of a pair of meshing gears the arrangement being such that the coversection may be removed without disturbing the bearings. 9o

2. A gear-casing consisting of the following elements; a cup-shaped section carrying a pair of shaft-bearings one at an angle to the other, a registering section arranged to inclose both of said bearings and to form with the first section a chamber for the reception of a pair of meshing gears, and a step-bearing carried by said second section in line with one of the bearings carried by the first section.

.3. .A gear-casing consisting of the follow- 1go ing elementsg'a cup-shaped section carrying a pair of shaft-bearings one at an angle to the other, a registering section arranged to inclose both of said bearings and to form with the first section a chamber for the reception of a pair of meshing gears, and an intermediate wail separating the gear-chamber from the chamber containing one of said bearings the said registering` section beingrcmovable without disturbing the bearings.

4. A gear-casing consisting of the followingr elements; a cnpshaped section carrying a pair of shaft-hearings one at an angie to the other, a registering section arranged to inclose both of said bearings and to form with the first section a chamber for the reception o f a pair of meshing; gears, an intermediate wail separating.;` the gear-chamber from the chamber containing one cfs-aid bearings,and a stepbearing carried by the second section in line with the other bearing of the first section.

5. A-gear-casing consisting of a section 5 having bearings 11 and 14 one at an angle to the other, and section 6 forming, with section 5, a gear-receiving chamber 2 and bearingchainber 23,' and a wail 21 separating said chambers.

6. A gear-casing consisting of a section 5 having bearings 11 and 14 one at an angleto the other, a section 6 having a wall 2l forming, with section 5, a gear-receiving chamber 22 anda bearing-cham ber 23, doors 25 and 26 furnishing access to said chambers, guard 28, and conduit 27.

'7. A gear-casing consisting of a section 5 having bearings 11 and 14 one at an angle to the other, a section 6 having a wall 21 forming, with section 5, a gear-receiving chamber 22 and a bearing-chamber 23, doors 25 and 26 furnishing access to said chambers, guard 28, conduit 27, and bearing 18 carried by section o'.
